 I put 2 links for video of the first cut I made.

That's the result. But I found out that X and Y weren't squared at all.

This took me a very long time to decide how to fix it. I did make 2 holes in the frame so I could reach the screws holding the X and Y axis together.

I got it now within 0.01mm. But the ball screw of the X axis has little wobble, which tilts the Z axis about 0.02mm at each turn on X. I crashed it once badly.
